UNLOADER FOB BOTTLE-WASHERS. v

eeann,

Original application filed November 22, 1915, Serial No. 62,706. Divided and r 9, 1919. Serial No. 302,882.

i 5 State of Wisconsim'have invented new and useful Improvements in Unloaders for Bottle-Washers,-of which the following is. a description, reference being had to the accompanying drawings, which are a part of This invention has for its object to provide a bottle washing machineof the type in which the bottle conveyor is given continuous traveling motion, and the washing 15 and brushing. mechanism is given a reciprocating travel to cooperate with the bottles successively while the latter are traveling, such type of bottle washer being exempllfied by Patent No. 1,095,290 to Daniel Another object of the invention is to provide such a machine with an electrically lighted inspection discharge chute onto which the washed bottles are deposited from theconveyer chain of bottle carriers.

Another object of the invention is to provide an automatic unloading means for shifting the bottles from the inspection chute onto a conveyer for removing them from the machine.

This application is a continuation and di vision of, that is contains subject matter taken from, my co-pending application, Serial No. 62,706, filed Nov. 22, 1915, for hotthe washing machine.

With the above and other objects in view the invention consists in the unloader for bottle washers as herein claimed and all equivalents.

40 Referring to the accompanying drawings in which like characters of reference indicate the same parts in different views: 7

Figure 1 is a side iew of an unloading mechanism for bottle washing machines constructed in accordance with this invention;

and,

Fig. 2 is a similar view showing the unloader in its raisedposition.

In these drawings 15' indicates the frame of a bottle washing machine or the like, only the discharge end thereof being shown. A suitably operated cam shaft 17 is jour'naled i the frame and sprocket wheels 19 are Specification of lietters Patent.

Patented Jur 5, 1921,. this application filed June mounted on a shaft also journaled in the are carried thereby in an inverted position;

At this end of the machine is an.inspection I. I

rest and unloading mechanism into 'which the bottles'are'dischaged from the bottle carriers 23 as they pass around the sprockets 19 Arms 97 adjustably mounted on thesides of the frame support carry at, their ends a sheet metal inspection box 98 whichis lighted by electric lamps 99 in the bottom thereof and support stationary inclined guide rods 100 down which the bottles are adapted'to slide on leaving the bottle car riers 23. The bottles are assisted in their disengagement from the bottle carriers .23 by the action of a'suitably driven discharge roller 101 against'which they contact after leaving an adjustable stationary curved bottle discharge guard. 102 which is in position to engage the bottoms of the bottles and prevent their falling from the carriers before reaching the roller 101. Journaled across the inspection box 98 is a shaft 103 carrying 'a frame of parallel arms 104, which at the time the bottles slide down the chute rods 100 are in position to receive them- As shown in Fig. 1 the bottles come to rest by engaging stationary bent spring stop fingers 1 105. A crank on the shaft 103 is connectedv by a link 106 with a cam lever 107 which is pivotally mounted on the arm 97 A roller 109 on the cam lever 107 travels in a cam groove 110 of the cam gear 27 and with each ,eycle of operation of the machine, for each row of bottles on the carrier, causes the shaft 103 to swing upwardly to the position shown in Fig. 2, thereby causing the discharge frame. 104 to lift the bottles by sliding them along the-carved stop fingers 105 and onto a traveling conveyor belt 108 by means of which they are carried upright to the filling machine.

Before the next row of bottles is ready to be discharged into the inspection box 98 the frame 10a is returned to its position for receiving them, and by the one row of bottles in their travel around the 1. In a bottle washing machine having a traveling bottle conveyer, inclined parallel rods forming an inspection chute in posltion to receive the bottles from the conveyer, the lower part of the inspection chute bemg pivotally mounted, a stop for limiting the sliding movement of the bottles on the inspection chute, a discharge conveyer, and means for swinging the lower part of the inspection chute for moving the bottles along the stop,- onto the discharge conveyer.

2. In a bottle washing machine having a traveling bottle conveyer containing bottle carriers adapted to hold inverted bottles by means of the necks thereof, a guide means around which the conveyer travels, and a suitably operated roller engaged by tge m e means to withdraw them from the ottle carriers.

3. In a bottle washing machine having a traveling bottle conveyer with bottle carriers contaming openings to hold the necks of in- 'verted bottles, a guide means around which the conveyer travels, an arc-shaped guard member in position to. prevent the bottles leaving the bottle holders before reaching their discharge position, and a suitably operated roller engagedlby the bottles in their ,..d1scharge position for withdrawing them from the carriers.

4. In a bottle washing machine, a traveling bottle conveyer having bottle carriers with openingsin which the necks of inverted bottles fit, a guide means around which the conveyer travels downwardly, an inclined chute in the path of the bottles as they turn around the guide means to conduct them away from the bottle carriers in an inclined position with their necks uppermost, a stop at the end of the chute against which the bottles come to rest, a bottle support, and

means for sliding the bottles over the stop and onto the bottle support.

5. Ina'bottle washing machine, a bottle conveyer having bottle carriers adapted to hold inverted bottles by means of their necks, guide means around which the conveyer passes downwardly, an inclined chute in the path of the bottles as'they pass around the guide means and adapted to conduct them away from the conv yer, a saitablydriven aaeaasa roller at the up er end of the chuteagainst which the bott es bear, the turning of the roller serving to draw the bottles out of the carriers and onto the chute, a stop against conveyer passes downwardly, an arc-shaped guard member in positiolgto bear on'the bottoms of the bottles after the bottles pass around the guide means he end a horizontal position, an inclined chute 1n thepath'of the bottles and adapted to be engaged thereby after the bottles pass beyond the guard member to conduct the bottles from the conveyer in an inclined position with their necks uppermost, a stop against which the bottles come to rest, a bottle rest, and a suitably operated swinging frame to' slide the bottles over the stop and onto the bottle rest.

7. In a bottle washing machine a traveling bottle conveyer havingbottle carriers adapted to hold inyerted bottles by means of their necks, guide means around which the conveyer travels downwardly, an inclined chute in the path of the bottles as" they travel around the guide means and adapted to conduct the bottles from the conveyer in an inclined position with their necks uppermost, a stop against which the bottles come to rest in such inclined position, an inspection box surrounding the bottlesas they rest on the chute against the stop, means within the inspection box for showing a light through the bottles, and means for movmg the bottles outof theinspection box.'-.

8. In a bottle washing machine a traveling conveyer having bottle carriers adapted to hold inverted bottles by means of the necks thereof, guide means around which the conveyer travels downwardly, an in clined slatted chute in the path of the bottles as they travel around the guide means and adapted to conduct the bottles away from the conveyer-in an, inclined position with.

their necks uppermost, a stop against which the bottles come to rest in this position, a discharge frame forming an extension of the chute at thelower end thereof and on which the bottles rest when they engage the stop, a discharge conveyer, and means for swinging the discharge frame to slide the bottles over the stop and onto the discharge conve er. 1 r
